. Application filed December 9,1905. Serial No.' 291,126.

.posed or assembled temporarily in line, the

composed line presented between two jaws or abutments which limit itsfinal length, the line finally justified by expanding the double wedgespacers seated in the line, as shown, for example, in Letters Patent ofthe United States, No. 436,532. In. these machines the composed linesuspended in a vertically-11lovable carrier, known as the fii'stelevator,'

is lowered by gravity to casting position between the two confining-jawsprior to justification.

It sometimes happens that the operator will compose the unjustified lineto such length that it will not'pass readily between the confining-jaws,and in such case there'is a liability of the end matrices beingdisplaced or thrown out of alinement by the frictional contact with thejaws. The aim of the present invention is to overcome this difficultyand to prevent the composed line of matrices from passing between thejaws in the event of its eing of excessive length. To this end I arrangeone of the confining-jaws and its 0 crating mechanism in such mannerthat t e jaw is advanced toward its companion previous to thepresentation of the matrix-line, so

that the distance between the jaws is for the 1 time being less than thelen th of the 'ustifi'ed line, so that the entrance of the line etweenthe jaws. is impossible. This fact makes it necessary for the operatorto remove the superfiuous matrices and in practice leads to his. settingthe line in the first instance of suitable length. The distance to whichI move the jaw beyond its final position, although Sllfllcient toprevent the entrance of the long line,

is not such as to prevent the entrance of proper lines,- which can bejustified or expand= ed to the predetermined length.

My invention may be carried into effect by any suitable mechanism. Theparts may be varied'in form-and arrangement to adapt them for use in thedifferent linotype-machines now known in the art.

In the accompanying drawings 'l have shown my improvement embodied 111;a Mergenthaler linotype-machine, containing the jaw-adjusting mechanismof the character shown in the application of R. M. Bedell for LettersPatent of the United States, filed September 12, 1905, SerialNo.278,194, the

mechanism shown differing from said application mainly in that it isadapted to carry the movable aw inward or forward beyond its finaloperative-point, whereas in the earlier mechanism its movements ceasedvat the final operative point.

Fig. 3 isa face view of the two line-confining jaws, their actuating devices, andthe first elevator with the matrix-line therein, the I iiiovable jawbeing advanced to such position as to prevent the descent of the matrX-linel Fig. 4 is asimilar View of the parts with the movable jaw in itsfinalpositionfat-the completion of the 'ustificat ion of the line. Fig.'5'

is a diagram illustratin the cam mechanism for actuating the jaw-ajusting devices.

Referring to the drawings, A represents a portion of the main frame,known' as the vise-franie; B. and C, the two matrix-confining jaws; D,the matrices in the composed line; E, the expanding spacers orjustifiers seated in the line; G, an adjustable rod seated against andsupporting the horizontally-slid ing jaw C; H, a block surrounding thevrod G I f i I and adjustably connected thereto by a removable toothedpin I.

J is a vertically-movable slotted wedgelencircling the rod Gfseated onone side against the block H and on the opposite side against abearing-plate K, which is in turn seated against a tubular supportingadj usting-screiv L, threaded into the main frame loosely around the rodG. The'wed 'e J is .urged constantly upward by a spring connecting itwith the main frame, and is drawn downward at proper timesiby a leverph'the end of which works in a vertical slot in thelower end of thewedge. The upper endof the wedge'is provided with two inclined or;

wedge faces k k, lying in reverse directions, so that whether forced"upward ,or drawn downward to an extreme position;it-will act to advancethe block'Hf'its rod G, and the matriii-confining jaw ,7 SO farasdescribed the parts are of the same construction as those in theapplication above referred to.

In carryin my inventioninto effect Icom bine with the lever p actuatingdevices which cause it to draw the wedge J downward until the jaw C isadvanced so farthat the distance between its face and the opposing faceof jaw B is less than the len th of the final or justified line, asshownin' ig. 3, so that the line of matrices supported in thevertically-movable second elevator M, if of proper length, is too longto descend between the jaws. Being arrested in its descent, the linecannot pass to the casting position, and the elevator M, in whichthe'llne is carried and by which the. casting mechanism is tripped intoaction, is prevented from descending far enough to start said mechanism.The wedge-actuating mechanism may be of any suitable character; but asshown in Fig. 5 it consists of a cam N, arranged to act on a roller onthe upper side of. the lever 29 for the purpose of depressing sameagainst the stress of the spring'lc An adjustingscrew k in the lower endof the wedge, upon which the lever acts, serves as a means of'adjustingthe throw of the wedge in advance of thev jaw C with required accuracy.K

In the operation of the machinethe jaw C is set in its forward andabnormal position; as shown in Fig. 3,. so that the descent of the mafrigc line is prevented if it is of excessive length, but not otherwise.After the line is loweredto its position between the jaws, as shown inFig. 4, the wedge rises and the jaw C retreats to such position that thedistance between it and the jaw B is equal to that of the justifiedline. The spacers E are then driven upward to effect the reliminaryjustification or expansion of the ine. .The casting operation may nowtake place but in order to secure more accurate alinement of thematrices it is usual to relieve the line from end pressure while theyare *being forced edgewise against the mold with the usual mechanism.For this.purpose I prefer to make'the cam, as shown,'of such form thatafter the preliminary justification has taken place the wedge wil riseto an intermediate osition and relieve the block H, so that the aw mayretreat slightly. After the mat-' rices are alined against the moldthewedge continues its upward motion to the position shown in Fig. 4,thereby setting the jaw C tween said jaws, and an automatic 'mechan--ismarranged to positively approximate the jaws to a distance less thanthe len th of the required line, and hold them in suc position.

during the presentation of the matrices, whereby the admission of tightor overset lines between the jaws is prevented.

3 2. In a'linotype machine, the combination of two matrix-confiningjaws, a composed line of matrices and spacers means for seating the linebetween the jaws, means for closing the jaws to a distance less than thelength of linedemanded, and thereafter opening them to said length, andmeans for justifying the.

line after said. separation.

3.. In a linotype-machi'ne, the combination of -m'eans for presentingcomposed lines of matrices and spacers, hneconfining jaws, means foradjusting the spacers to justify the lines between the jaws, and meansfor setting the aws: first, to a distance apart less than the requiredlength of line, thereafter to a distance equaLto the required length,and finally, to a greaterdi'stance apart to release the justified ine.

4. In a linotype-machine, the two matrixconfining jaws, in combinationwith a wedge.

. mechanism, actin to set the jaws, first, a distance apart less t anthe length or measure '-of the required line, and second, a distanceapart equal to the length of the line.

In testimony whereof I hereunto set my hand this'lthday-of December,1905, in the presence of two attesting witnesses.
